Clay Jensen returns home from school to find a mysterious box with his name on it lying on his porch. Inside he discovers thirteen cassette tapes recorded by Hannah Baker, his classmate and crush who committed suicide two weeks earlier.

On tape, Hannah explains that there are thirteen reasons why she decided to end her life. Clay is one of them. If he listens, he'll find out how he made the list.

Through Hannah and Clay's dual narratives, debut author Jay Asher weaves an intricate and heartrending story of confusion and desperation that will deeply affect teen readers.
